Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to prevent electrical short circuits.

2. Inspect and Repair Leaks

Tools Required: Socket set, torque wrench, oil catch pan, rags.
Sub-steps:
1. Lift the vehicle using a jack and secure with jack stands.
2. Inspect the oil pan, valve cover, and gaskets for leaks.
3. Tighten loose bolts and replace any worn gaskets or seals.
4. Clean any spilled oil and dispose of properly.

3. Replace PCV Valve

Tools Required: Pliers, socket set.
Sub-steps:
1. Locate the PCV valve in the engine bay.
2. Disconnect the valve from its hose and remove it from the engine.
3. Install the new PCV valve and reconnect the hose securely.

4. Address Engine Wear

Tools Required: Compression tester, multimeter.
Sub-steps:
1. Perform a compression test on each cylinder.
2. If low compression is found, consider replacing piston rings or cylinder head gaskets.
3. Reassemble the engine components and ensure all connections are secure.

5. Add Oil and Test

Sub-steps:
1. Reconnect the battery.
2. Fill the engine with the manufacturer-recommended oil type and level.
